The Pi Digit PI Day Apple Pie Recipe includes the first thirteen digits of Pi in the recipe.  The apple pieces are cut out into digits using cookie cutters.  The slits on top of the pie are cut out in the form of as many of the digits of Pi as you can fit on the circumference of the Pie.  The words DIAMETER, CIRCUMFERENCE, and 360 degrees are also included in the recipe as a shout back to the circle and the formula for Pi.  Your mom probably told you not to play with your food, but go ahead and search for as many of the digits of Pi as you can find as you eat PI.  ENJOY!!!!
